var newPolygon = new GPolygon(ArrPt,"#ccff66",2,0.5,"#ff0033",0.5); map.addOverlay(newPolygon); var Parea = newPolygon.getArea(); alert(Parea); } l getArea():取得Polygon所围的面积(Google Maps会根据投影自己计算),返回数值类型。 l getBounds():取得Polygon的边界,返回GLatLngBounds类型。

可以使用Google Maps JavaScript API提供的Polygon对象来定义特定区域的边界。然后,通过在搜索请求中使用边界参数,可以将搜索结果限制在该区域内。 以下是一个示例代码,演示如何使用Google Maps API将搜索结果限制在特定区域: 代码语言:txt 复制 // 定义特定区域的边界坐标 var areaBounds = [ { lat: 37.7749, ...
{lat:40,lng:-110},zoom:4,});constapiKey='YOUR_API_KEY';constairqualityType='UAQI_RED_GREEN'// AirQuality API heatmap typeconstdeckOverlay=newGoogleMapsOverlay({layers:[// Heatmap Tiles layernewTileLayer({id:'heatmap-tiles',data:'https://airquality.googleapis.com/v1/mapTypes/'+ heat...
由于Maps API 尚未提供解决方案,并且手动填写坐标与任何人无关,因此这里有一个替代方案。在 GIS 网站上找到了这个答案——绝对的救星(可以节省 jurihandl 绘制卡尔加里的大量时间,上面;D): You can get polygon coordinates in json for using with googlemaps using openstreetmap. Go tohttp://nominatim.openstr...
I am a bit of a beginner at google maps api. I managed to let the user to draw a polygon on the map and then I want to get the coordinates on the drew polygon. I have used the following segment of code but it gave me the following error Uncaught TypeError: Object [object Object...
2) The outer line (a blue one) is the polygon I want to get by adding 1 km (or some other distance) to every terminal point of the initial polygon. How may I achieve it? Does Google Maps API provide some special functions? I'm not asking for ready solution, please give me an ad...
由于多边形区域可能包含多个单独的路径,因此 Polygon对象的paths属性指定了一个数组数组,每个数组类型都是type MVCArray。每个数组定义一个单独的有序LatLng坐标序列。 对于仅包含一条路径的简单多边形,您可以Polygon使用单个LatLng坐标数组 构造一个。将Maps JavaScript API存储在paths属性中时,构造后会将其转换为数组数组...
Polygons are used to highlight a particular geographical area of a state or a country. You can create a desired polygon by instantiating the classgoogle.maps.Polygon. While instantiating, we have to specify the desired values to the properties of Polygon such as path, strokeColor, strokeOapaci...
I believe that Google does not expose the information about the suburb’s boundary. You could store the points in boundary yourself, and display them with a Polygon. 和 The Google Maps API v3 doesn’t do that. You need to find a different data source or manually determine the coordinates....
